Fire, scientists agree, helped give rise to a successful, thriving human population by providing heat for cooking and protection from the cold.
But they don’t agree【C1】______when humans began using fire. Some researchers argue that it【C2】______more than a million years ago when early humans【C3】______their way to Europe from Africa, and【C4】______say it happened much later. Now, a new study reveals that humans did not【C5】______fire until about 400 000 years ago.
Two archaeologists(考古学家)in the US report their【C6】______in the current issue of the Proceedings of the National Academy of Sciences. They looked at excavation(发掘)reports and studies from 141 sites in Europe that were【C7】______1.2 million and 35 000 years old. They think there is no clear evidence of【C8】______fire use until about 400 000 years ago. In Africa,【C9】______there are several sites where there was evidence of fire, those may have been【C10】______fires that occurred in the African grassland.【C11】______, there are also sites older than 400 000 years in Europe that indicate the【C12】______of humans, with the oldest, in Spain, more than a million years old. This means that【C13】______Europe’s extreme winter climates, early humans found a way to【C14】______without the warmth of a fire.【C15】______the researchers mention, early humans are【C16】______and persistent(坚持的). But some researchers【C17】______that it is still a puzzling explanation and it still【C18】______some serious thinking about how【C19】______the human being could have survived on a seasonally【C20】______food supply despite having small teeth and small guts. Up to now, no one has solved this problem yet.
【C8】
选项
A、familiar
B、experienced
C、skillful
D、habitual
答案
D
解析
此空应该与fire use构成搭配。结合备选项,可以判断科学家们寻找的是人类习惯用火的证据而不是用火的技巧问题。所以选habitual。familiar意为“熟悉的”;experienced意为“有经验的”;skillful意为“有技巧的;巧妙的”。
